Application led .Tune la,

illy invention relates to improvements in rail locks, and has 'for its object a provision ot' an improved c oi'istruction olf this characterl by means ot' which adjacent raid ends at the joints or gaps therebetween, may be securely and positively locked together so as to in. eii'ect constitute a continuous rigid construction, which is capable ot' economical manufacture and highly efficient in use.

Other objects will appear hereinafter.

, The invention consists in the combinations and arrangements oii parts hereinafter described and claimed.

The invention will be best understood by reference lo the accompanying drawings Yforming a part et' this specification, and in which,

Fig. 'l is a top plan view, shown partially in horizontal section. of a rail lock o1' jointembodying the invention;

Fig. 2 is a side view of the saine;

Fig. 3 is a transverse section taken through the rail adjacent said joint;

F ig. l is a top plan view of one of two cmuplementary locking parts;

Fig. 5 is a side view corresponding with Fig. Ll; and

Fig. 6 is an end View corresponding with llig. Y5.

The preferred term et construction as illustra-ted in the drawings comprises two identical complementary parts each consisting;` of a main base plate 7 adapted and arranged to rest under the hase of a railroad rail and provided at opposite sides with perforated lugs S tor the reception of spikes to secure the saine to the ties. Each main base plate. 7 provided at one side with a` longitudinal projection 9 of a width sulostantially equal to one-half oi the width of the base of the rail7 thus leaving a gap or recess 9 Jfor the reception ot' the corresponding extension 9 on the complementary part. Each main base plate 7 is also provided at its edge opposite the extension 9 with an upwardly and inwardly extending lip or shoe l0 adapted to engage under the correspending side of the head of the rail as shown. Each shoe 10 is provided with a longitudinal extension ll ot the same length as the extension 9 and adapted and arranged to constitute a side plate resting flat against the corresponding side of the rail. Each eX- tension 1l is provided with bolt holes 12 and a slot 13 as shown.

In use two of the parts thus provided are Loon.

oppositely arranged at each. vrail joint as shown, with the extensions 9 interlocking ylaterally with each other and constituting a complete level support fory the base 1.4L ot the rails with thev extensions ll resting flat against the sides of the webs l5 of the rails, and with the slices l0 resting against the corresponding undersides oi' the rail heads 1G as shown. Bolts 17 are passed through the holes l2 and the slots 13 thus securing the rail ends rigidly together but the slots 13 permitting suflicient longitudinal movenient to take care of expansions and contractions of the rails, the parts being securely spiked to the tics by means of 'the lugs By this arrangement a simple and effective rail lock or joint is provided which will securely and rigidly join the ends of the rails and it is economical in manufacture and highly eilicient in use. The specilic form and arrangement of parts vis a simple and effective one for the purpose.

While I have illustrated and' described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations ancA inodiiications as come within the scope of the appended claims. y

Having described iny invention, what I claim as new and desire to secure by Letters Patentis:

1. A device of the class described comprising two complementary parts, each part comprising a base plate to rest under a rail and a side plate spanning the gap between adjacent rail ends; lateral enlargements connectingy the base plate and side plate and contacting with the ball and web of the rail to reenforce the latter at the point oit' connection ot' a pair of rail sections, bolts securing said side plates to said rail webs, substantially as described. a longitudinal extension formed on each of the lateral enlargements oli'set from the latter so that they will lie against the web of the rails, and fastening-s passing through the longitudinal extensions and railway webs.

2. A device of the class described com-v prising two complementary parts, each of said parts comprising a main base plate adapted to rest under a rail and provided at side with perforated lugs for the reception ot' spikes; a longitudinal extension on each base plate substantially equal in width to one-half of the width of the base ot' the rail and adapted to rest under the corresponding half of said rail base; an upwardly and ink wardly inclined shoe at the side of said base plate opposite said longitudinal extension, said shoe being adapted and arranged to engage under the corresponding head of the rail; a longitudinally extending extension on the edge ot' said shoe adapted to rest llat against the corresponding side ot the rail web, said extension being of substantially the saine length as said base plate extension and perforated for the passage'of bolts, two of said complementary parts being arranged at a rail joint to span the gap between adjacent rail ends, with said longitudinal base plate extensions interlocking with each other laterally and said shoe extensions resting` against opposite sides of the rail webs; and bolts passed through said shoe extensions and said rail webs on opposite sides of the joint gap, substantially as described.

3. The combination with the meeting ends ot' a pair of rail sections, of means for connecting and reen't'orcing such sections at their meeting ends comprising a pair of base plates upon which the rail ends are adapted to rest, an upwardly inclined lateral enlargement carr-ied by each base plate atthe opposite sides of and engaging the rail sections at the opposite faces ottheir webs and contacting with the underface of the rail heads, a forwardly extending longitudinal extension formed on each of the enlargements and offset from the latter whereby they are disposed against the face of the web of the rails and bridge the joint, and removable fastenings extending through such longitudinal extensions and the rail sections.

In testimony whereof: l:k have signed my name to this specification.

WILLIAM KUPKE.
